Does the American system bear any resemblances to Rome during its imperial period? Paul Krugman, who has cheered virtually every step toward empire (we're not talking foreign policy here; we mean empire as in a system dominated by a single man or a single centralized government), has the gall to be concerned all of a sudden. This is episode 66 of my sister podcast, Contra Krugman.

Documentary filmmaker Cassie Jaye began her project on the men's rights movement as an unsympathetic, almost uncomprehending observer. After letting representatives of that movement tell their story, she had the honesty to admit there was merit in their position.

Shari Spivack, president of the Second Amendment Women Shooting Club, discusses gun rights from the point of view of someone who trains people in firearms usage rather than engages in political activism. Some people should probably stuff envelopes, I guess, but without people like Shari, what have we got?

Michael Rectenwald, a professor of liberal studies at New York University who describes himself as a lifelong left-liberal, took to Twitter not long ago to express his disgust with political correctness, safe spaces, and SJW intimidation.

Is libertarianism all about the Nonaggression Principle, or are there supplementary ideas a libertarian must also hold because they uphold the free society?

Entrepreneur and blogger C. Jay Engel joins me to discuss.
